Product catalog summary
Specifications:
The UTL UN Type A Couplings are constructed from cast iron GG 25 and feature replaceable elastomer parts without the need to remove the coupling. They are torsionally flexible, maintenance-free, and vibration-damping. The couplings are axial plug-in and fail-safe, with a finish bore according to ISO fit and a feather keyway according to DIN 6885 sheet 1 - JS9 and P9.
Dimensions and Capacities:
The document provides detailed dimensions and capacities for various sizes (110 to 250), including nominal and maximum torque (Nm), maximum speed (rpm), pilot bore (mm), and maximum bore diameters (Ød1, Ød2). The dimensions are specified in millimeters for ØD, ØD1, ØD2, L, L1, L2, L3, L4, E, and H.
Materials:
The hub is made of cast iron, and the cushion is made of nitrile rubber with a hardness of 80° Shore A. The cast iron conforms to DIN 1693 GG 25, and the nitrile rubber conforms to ASTM D2000 BG 810.
